    Notes: Abstract Male Wistar rats fed for 60 days a glucose diet containing 17.5 mmol hexachlorobenzene/kg show a less pronounced increase in serum parameters and microsomal cytochrome P-450 concentration and a lower decrease in liver plasma membrane 5′-nucleotidase, K+, Na+- and Mg++-adenosine triphosphatase activities than the controls fed standard diet + hexachlorobenzene. Addition of 10% ethanol to the drinking water eliminates the “glucose effect”. The glucose diet and ethanol exert contrasting effects on microsomal enzyme induction and liver plasma membrane damage in hexachlorobenzene intoxication.

    Notes: Abstract Generation of 946 nm radiation from a commercially available, flashlamp-pumped Nd:YAG laser was investigated. By suppression of the high-gain 1.064 μm transition and with a specially designed cooling system, a stable emission at 946 nm was achieved in the temperature range 300–240 K. At a repetition rate of 10 Hz laser output powers of 100mW and 500 mW were obtained at room temperature and 240 K respectively. The temperature dependence of unsaturated gain, slope efficiency and pumping threshold were determined.

    Notes: Resonantly enhanced multiphoton ionization (REMPI) spectra of jet-cooled Xe2 are presented, covering the spectral region between ≈74 627 and 80 849 cm−1. Dimer ions produced by (2+1) REMPI excitation were mass selected in a linear time-of-flight (TOF) mass spectrometer. The vibrational and isotopic structure of several band systems dissociating to Xe* 5p56p and 5p55d asymptotes have been analyzed, many unambiguously for the first time, and molecular constants derived. Equilibrium bond lengths were estimated from Franck–Condon calculations. Insight into excited state predissociation was also obtained by recording atomic TOF excitation spectra. © 1994 American Institute of Physics.

    Vacuum ultraviolet laser/time-of-flight mass spectroscopy: Ion-pair spectra of 79Br35Cl (1994)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A newly built vacuum ultraviolet (VUV) laser/time-of-flight mass spectrometer is described, which has been used to record the first vibrationally and rotationally resolved spectra of the E0+ ion-pair state ←X0+ ground state transition of jet-cooled bromine monochloride BrCl, near 145 nm. The mass resolution of the instrument (m/Δm≈1000) was sufficient to obtain single isotopomer data. Preliminary results for 79Br35Cl are reported. Like other interhalogens, BrCl vibronic band intensities vary widely in the VUV, presumably as a result of excited state perturbations. This scenario has been corroborated by the observation of an irregularly spaced vibrational progression, and the irregular behavior of the excited state rotational constants as a function of v'.

    Mass-resolved multiphoton ionization spectra of XeKr in the region of Xe* (6p,5d) (1995)

    Notes: Single isotopomer (2+1) resonantly enhanced multiphoton ionization (REMPI) spectra of jet-cooled XeKr have been recorded using time-of-flight (TOF) mass detection. Vibrational analyses for several transitions involving excited states that dissociate to Kr(1S0)+Xe* (6p,5d) between 77 560 and 80 150 cm−1 are reported for the first time. Equilibrium bond lengths were established by Franck–Condon calculations, while excited state symmetries were inferred from excitation spectra recorded using circularly polarized light. A local vibrational perturbation evident in the dominant band system dissociating to Kr(1S0)+Xe*5p56p[5/2]2 has also been analyzed. The identity of the perturbing state is proposed, based in part, on predissociation spectra obtained by monitoring atomic fragments in TOF detection. © 1995 American Institute of Physics.

    Notes: (2+1) resonantly enhanced multiphoton ionization spectra of jet-cooled Kr2 between ≈91 800 and 94 100 cm−1 have been recorded. Single isotopomer excitation spectra were obtained using time-of-flight mass detection. Vibronic structure for several Rydberg ← ground state transitions involving excited gerade states which dissociate to Kr+Kr* (4p55p) have been unambiguously analyzed for the first time, and molecular constants derived. Bond lengths were estimated from Franck–Condon calculations. These results compare favorably with recent ab initio calculations. Excited state predissociation effects were inferred from excitation spectra obtained by monitoring atomic daughter fragment ions in TOF. © 1995 American Institute of Physics.

    Notes: Eight band systems of jet-cooled Xe2 between 83 763.9 and 80 149.8 cm−1 involving gerade excited states that dissociate to Xe(1S0)+Xe*5d[3/2]10, Xe(1S0)+Xe*5d[5/2]30, Xe(1S0)+Xe*5d[5/2]20, Xe(1S0)+Xe*5d[7/2]30, Xe(1S0)+Xe*5d[7/2]40, and Xe(1S0)+Xe*6p[1/2]0 have been characterized using (2+1) resonance enhanced multiphoton ionization/time-of-flight mass spectrometry, many for the first time. Excited state vibrational numbering and constants, including dissociation energies were obtained from bandhead measurements made from separate single isotopomer spectra. Bond lengths were estimated from Franck–Condon factor intensity simulations, while excited state electronic symmetries were deduced primarily from polarization measurements. In three instances, energy barriers due to double well potential energy curve formation are identified. © 1997 American Institute of Physics.

    Vibronic analysis of the ion-pair (E0+)←ground state (X0+) transition of BrCl (1997)

    Notes: Vibrationally and rotationally resolved spectra of the first-tier E0+(v′) ion-pair state ←X0+(v′′=0) ground-state transition of jet-cooled BrCl near 145 nm were recorded by exciting the halogen with a tunable vacuum ultraviolet "laser" generated by four-wave difference mixing in Kr gas, and detecting the ions produced by (1+1′) resonance enhanced multiphoton ionization in a linear time-of-flight mass spectrometer. J-numberings for thirty individual isotopic bands were established by ground-state combination differences, and per band rotational constants were derived. Extensive perturbations precluded the determination of an unambiguous absolute v′-numbering for the observed features or equilibrium rotational constants. However, excited-state vibrational isotope shift measurements do indicate that transitions from v′′=0 of the ground-state probe vibrational levels between v′=173 and 205. © 1997 American Institute of Physics.

    Vibronic analyses of the mass-resolved NeXe spectra near Xe*(6p) (1997)

    Notes: New mass-resolved two-photon spectra of NeXe involving molecular Rydberg states that dissociate to Ne+Xe*(6p) have been recorded using the combined techniques of (2+1) resonance enhanced multiphoton ionization and time-of-flight mass spectrometry. Excited state symmetries were deduced from separate spectra recorded with linearly and circularly polarized light. Vibronic analyses show that most of the excited states in this spectral region are essentially repulsive except for shallow minima whose electronic origins lie above their asymptotic dissociation limits. The magnitude of the potential humps for the excited states have been estimated. These results are rationalized in terms of an excited state bonding scheme that is dominated predominately by the interplay between repulsive exchange interactions and attractive long-range forces. © 1997 American Institute of Physics.
